Considering how much Salt Lake City has supported metal music through the years, it's surprising that Iron Maiden hasn't visited more often. The British metal pioneers still fill stadiums around the world, and they regularly stopped in SLC back in the '80s. The rarity of the occasion makes this Maiden show Wednesday feel more like a "must-go" than most summer concerts. The guys in the band are old enough that you gotta figure they'll stop touring in the next few years, making this potentially the last time Utahns will get to hear the powerhouse vocals of Bruce Dickinson, the rumbling, creative bass work of Steve Harris, and the undeniable tunes like "Run to the Hills," "Two Minutes to Midnight" and "The Trooper." Prog-metal dudes Coheed & Cambria open the show.

Of all the Twillight Concert Series shows this summer, this is the one I've been looking forward to the most. My Morning Jacket is one of the best rock and roll bands going right now, and live on stage is where the Kentucky-bred crew truly thrives. I became a fan after seeing them at the Zephyr Club years ago, when singer Jim James (he of the otherworldly croon) performed the entire show with a stuffed parrot attached to the shoulder of his coat--never mentioning the odd prop once. In the years since, My Morning Jacket has come through Club Sound and The Depot, but they've blown up to a new level, headlining festivals like Bonneroo and creating increasingly experimental new music on albums like Circuital and Evil Urges. This is a Twilight show you'll want to be on time for, too, thanks to opener Joshua James--a Utah local whose music has taken him on national tours to play for a much-more-than-Utah fanbase.
